TECHNICAL FIELD

[0001] The present invention relates to a novel difluoroalkene derivative and a pest control agent containing the same as an effective ingredient.

BACKGROUND ART

[0002] It has been already reported that a difluoroalkene derivative has an activity as a pest control agent. For example, JP-A-2000-38379 discloses a linear difluoroalkene derivative esterificated with pyridine carboxylic acids. JP-A-2000-86636 discloses a linear difluoroalkene derivative esterificated with pyrazole carboxylic acids. JP-A-2000-186073 discloses a linear difluoroalkene derivative esterificated with thiophene-2-carboxylic acid, furan-2-carboxylic acid, 1,4-pyrimidine-2-carboxylic acid or quinoline-4-carboxylic acid. JP-A-2000-198769 discloses a linear difluoroalkene derivative thioesterificated or dithioesterificated with benzoic acid or pyridine carboxylic acids. U.S. Pat. No.5,081,287 discloses a linear difluoroalkene derivative esterificated with an alkanecarboxylic acid, an alkenecarboxylic acid, an aromatic carboxylic acid or the like. WO97/08130 discloses a linear difluoroalkene derivative esterificated with substituted benzoic acids (see JP-A-11-510474).

[0003] All of these difluoroalkene derivatives have a 1,1-difluoroethylene (—C═CF₂) type of difluoroalkene end group.

[0004] Also in DPO No.4122506 discloses a 2-methyl- or 2-ethyl-1,1-difluoroethylene type of difluoroalkene derivative esterificated with various carboxylic acids, wherein a heterocyclic carboxylic acid may be used as a carboxylic acid but no specific example is shown. In EP-A-432861 (see JP-A-4-154740) discloses a 2-methyl-, 2-ethyl- or 2-phenyl-1,1-difluoroethylene type of difluoroalkene derivative esterificated with various carboxylic acids, wherein heterocyclic carboxylic acids such as pyridine, triazole or chromene may be preferably used as a carboxylic acid, but no specific compound is exemplified.

[0005] Desirably, a pest control agent used for useful crops shows a sufficient pest control effect with small dose against various pests which have resistance to conventional pest control agents for agricultural or gardening use, and is highly safe for crops, natural enemies to the pests and mammals. From these viewpoints, conventional difluoroalkene derivatives are not necessarily satisfactory, and thus development of a pest control agent having a sufficient pest control effect and high safety has been demanded.

[0831] In using a compound of the present invention as an effective ingredient for a pest control agent, a compound of the present invention may be used as it is, but it can be transformed into various types of formulations such as emulsion, suspension, powder formulation, granule, tablet, wettable powder, water soluble powder, liquid drug, flowable type pesticide, granule type wettable powder, aerosol, paste, oil solution, opacifier, smoking agent, or the like, by compounding a carrier, a surfactant and other auxiliary agents generally used in a preparation as a pesticide auxiliary agent. Compounding ratio of these agents is, in general, 0.1 to 90 parts by weight as an effective ingredient and 10 to 99.9 parts by weight as a pesticide auxiliary agent.

[0832] A carrier used in preparation here is classified into a solid carrier and a liquid carrier. A solid carrier includes, for example, powders derived from animals or plants such as starch, activated carbon, soybean powder, wheat flour, wood flour, fish meal and dried milk, and inorganic powders such as talc, kaolin, bentonite, calcium carbonate, zeolite, diatomaceous earth, white carbon, clay, alumina, ammonium sulfate and urea. A liquid carrier includes, for example, water; alcohols such as isopropyl alcohol and ethylene glycol; ketones such as cyclohexanone and methyl ethyl ketone; ethers such as dioxane and tetrahydrofuran; aliphatic hydrocarbons such as kerosene and gas oil; aromatic hydrocarbons such as xylene, trimethylbenzene, tetramethylbenzene, methylnaphthalene and solvent naphtha; halogenated hydrocarbons such as chlorobenzene; amides such as dimethylacetamide; esters such as glycerin esters of aliphatic acids; nitriles such as acetonitrile; and sulfur containing compounds such as dimethylsulfoxide.

[0833] A surfactant includes, for example, metal alkylbenzenesulfonates, metal dinaphthylmethanesulfonates, alcohol sulfate salts, alkylarylsulfonate salts, ligninsulfonate salts, polyoxyethylene glycol ethers, polyoxyethylene alkylaryl ethers, polyoxyethylene solbitanmonoalkylates and silicone based surfactants.

[0834] Other auxiliary agent which can be used includes adhesives or thickeners such as carboxymethyl cellulose, gum Arabic, sodium alginate, guar gum, tragacanth gum, polyvinylalcohol or the like; defoaming agents such as metal soap; property improving agents such as aliphatic acids, alkylphosphate salts, silicone and paraffin; colorants; and the like.

[0835] In practical use of these preparation, they may be used as they are or by diluting with a diluent such as water or the like to a specific concentration. Various preparations containing a compound of the present invention or diluted form thereof may be applied by generally adopted processes, that is, spraying (for example, atomization, misting, dusting, granule spraying, water surface scattering and application in a box), soil application (for example and mixing, irrigation), surface application (for example, coating, powder spraying and covering), dipping, poison bait, smoking, or the like. It can also be fed by mixing the above-described effective ingredient into feed for domestic animals to inhibit generation and growth of vermin, in particular, noxious insects in the excreta. It may also be applicable by small amount of spraying in ultra-high concentration. In this method, 100% of active ingredient can be included. Compounding ratio of an effective ingredient is suitably selected as appropriate, but 0.1 to 20% (by weight) is suitable for powder and granule preparation, and 1 to 80% (by weight) is suitable for emulsion preparation and wettable powder.

[0836] The pest control agent of the present invention is used, in general, in a concentration of an active ingredient of 0.1 to 5,000 ppm, when the agent is used in diluted state with a diluent. In the case when the agent is applied without dilution, an amount of the preparation to be applied for unit area is, but not limited to, 0.1 to 5,000 g per hectare as an active ingredient compound.

[0837] It is not to be argued that the compound of the present invention demonstrate sufficient effectiveness by itself, but it can be used by mixing with or together with other fertilizers or agricultural chemicals such as insecticides, acaricides, nematicides, fungicides, antiviral agents, attractants, herbicides and plant growth regulators, and such way of use may provide further beneficial effects.
